Adoption of rooftop solar panels has surged on the Caribbean island of Puerto Rico as it contends with high energy costs and frequent outages.

Why tiny solar projects play an outsized role in powering Puerto Rico

,

On a given sunny day in Puerto Rico, more than 37,100 rooftop solar installations—mounted atop homes, gas stations, malls and hospitals—churn out 255 megawatts of electricity.

That’s only about 2.5% of the island’s overall power generation. But collectively, the rooftops might be considered Puerto Rico’s largest clean power plant, dwarfing the 101-megawatt Santa Isabel wind farm, the island’s largest renewable generator.

As the US territory of 3.2 million people scrambles to shift to 100% renewables by 2050, much of the focus has been on utility-scale initiatives. In March, regulators conditionally approved 18 renewable power plants that should produce 884 megawatts by 2024. But even with that additional capacity, the island will still depend on fossil fuels for more than 84% of its electricity.

Gov. Newsom’s clean air regulators prioritize rooftop solar expansion in California climate action plan

SAN FRANCISCO – California’s top clean air regulators this week released a proposed plan to fight the climate crisis by cutting carbon dioxide emissions, with policy priorities including an effort to expand rooftop solar throughout the state.

The 11-point “Strategies for Achieving Success” draft plan responds to Gov. Gavin Newsom’s request for the California Air Resources Board, or CARB, to identify strategies for eventually making the state carbon neutral. On page 164 of the plan, CARB says:

  • Target programs and incentives to support and improve access to renewable and zero-carbon energy projects (e.g., rooftop solar, community solar, battery storage, and microgrids) for communities most at need, including frontline, low-income, rural, and indigenous communities.

California’s solar potential remains huge

California leads the nation with more than 1.3 million solar rooftops installed on homes, but the state also has potential for a lot more.

The state ranks second in the nation when measuring the percentage of solar panels on rooftops capable of installing photovoltaic systems.

Consumer comparison research firm InMyArea.com used data from Google’s Project Sunroof, which estimates the suitability of solar installations on the nation’s buildings, to calculate energy costs from the U.S. Energy Information Administration.
